NI contribution for work abroad in Hong Kong

I am an ordinary resident in UK in Y2023-2024. I had worked in Hong Kong in contract basis from Jun to Oct/23 (four months). Do I need to pay the Class 1 NI for this working abroad job? If yes, do I need through DCNI to submit the record. My worked company hasn’t any business office in UK. In addition, I need to submit SA102(employment) or SA106 (foreign income) for this case when I submit the self assessment for tax return.
